In a prior message I documented my woes in getting an NFS_ROOT xen going. I haven''t resolved those yet, want to try a different tack at this: If the group were to recommend a path of least resistance to showing migration/live migration, which configuration would it be?

This idea is intruiging... Suppose one has a set of file servers called A, B, C, D, and so forth, all running CentOS 6.5 64-bit, all being interconnected with 10GbE. These file servers can be divided into identical pairs, so A is the same configuration (diks, processors, etc) as B, C the same as D, and so forth (because this is what I have; there are ten servers in all). Each file server has

Hi, I think I''ve nearly evaluated all choices for which Virtualisation option to go to. Disappointed so far that I can''t get my PCI Cards visible in a guest, but never mind. On the same hardware (2 Gig RAM, AMD Athlon 64 3500 and a Fedora Core 8 i386 install), OpenVZ has a tendency to "freeze" up every now and again in SSH.KVM/Qemu seem to slow, Xen seems really

Is it possible to create a highly-available OCFS2 cluster (i.e., A storage cluster that mitigates the single point of failure [SPoF] created by storing an OCFS2 volume on a single LUN)? The OCFS2 Project Page makes this claim... > OCFS2 is a general-purpose shared-disk cluster file system for Linux capable of providing both high performance and high availability. ...but without backing-up

Hi, I want to combine all the above mentioned technologies. The Linbit pages warn not to use the drbd: VBD with HVM DomUs. This page however: http://publications.jbfavre.org/virtualisation/cluster-xen-corosync-pacemaker-drbd-ocfs2.en (thank you Jean), simply puts two DRBD devices in dual primary mode and starts Xen DomUs while pointing to the DRBD devices with phy: in the DomU config files.

I have an existing in-production LAMP server running Centos 5.1. It uses physical partitions on top of hardware RAID1, having / /home /var and /boot on separate partitions. We have a near-identical system I am thinking of bringing in as a DRBD/Heartbeat companion. One solution may be to use csync2 [http://oss.linbit.com/csync2/] on /etc and /usr/local (the only areas that will differ from

Hi all ! Is anyone using xen kernel + drbd 8.2.4 ? I don''t know exactly if my problems come from the addition of the two packages, or from drbd 8.2.4, but I encoutered kernel panic 2 times when trying to do first sync of drbd resources :s Cheers, -- Serge Dewailly _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Hi all, We're looking at deploying a small Xen cluster to run some of our smaller applications. I'm curious to get the lists opinions and advice on what's needed. The plan at the moment is to have two or three servers running as the Xen dom0 hosts and two servers running as storage servers. As we're trying to do this on a small scale, there is no means to hook the

Hello all, At our office a have a server running 3 Xen domains. Mail server, etc. I want to make this setup more redundant. There are a few howtos on the combination of Xen, DRBD, and heartbeat. That is probably the best way. Another option I am looking at is a piece of shared storage, a machine running CentOS with a large software RAID 5 array. What is the best means of sharing the storage?

I've run into a problem mounting an OCFS2 filesystem on a DRBD device. I think it's the same one discussed at http://lists.linbit.com/pipermail/drbd-user/2007-April/006681.html When I try to mount the filesystem I get a ocfs2_hb_ctl: I/O error: [root at node-6A ~]# mount -t ocfs2 /dev/drbd2 /cshare ocfs2_hb_ctl: I/O error on channel while starting heartbeat mount.ocfs2: Error when

Dear All, Currently using RHEL6 Linux and Kernel Version is 2.6.32-71.el6.i686 and DRBD Version is 8.3.10 DRBD is build from source and Configured DRBD with 2 Node testing with Simplex Setup Server 1 : 192.168.13.131 IP Address and hostname is primary Server 2 : 192.168.13.132 IP Address and hostname is secondary Finally found that drbd0, drbd1 mount failed problem *Found some error messages

Hello, This morning I noticed the following output from "yum update": Installing: drbd82 x86_64 8.2.5-1.el5.centos extras 209 k replacing drbd.x86_64 8.0.11-1.el5.centos As far as I'm aware DRBD works fine for me. Is there a way I can find out about the new release and weather I should upgrade? I can't figure out the CentOS issue tracking system

Hello list, I want to use shared volumes between severall vm''s and defenetly don''t want to use NFS or Samba! So i have three options: 1. simulated(software-) iscsi 2. GFS 3.

I''ve been brainstorming... I want to create a 2-node HA active/active cluster (In other words I want to run a handful of DomUs on one node and a handful on another). In the event of a failure I want all DomUs to fail over to the other node and start working immediately. I want absolutely no single-points-of-failure. I want to do it with free software and no special hardware. I want

Hi all. I am currently working for a hosting provider in a 100+ linux hosts' environment. We have www, mail HA solutions, as storage we mainly use NFS at the moment. We are also using DRBD, Heartbeat, Corosync. I am now gathering info to make a cluster with: - two virtualization nodes (active master and passive slave); - two storage nodes (for vm files) used by mentioned virtualization nodes

I had to deal with ransomware at the end of April. One of the PCs on my customer's network was infected by opening a realistic looking email apparently from a genuine supplier to the company and personally addressed. The infection occurred on Wednesday, but encryption of the server only took place late on Friday afternoon, presumably having obtained encryption keys from the criminals. The

Regardless of the filesystem (i''ve used reiserfs, xfs, ext3), whenever I mount a fresh DRBD partition I get some nasty kernel messages. This is under Debian Sarge, Xen kernel 2.6.11.12-xen0 (dom0) using DRBD v0.7.11 (pulled from Debian "testing"). This is what I did to create the partition. On both nodes I created a new LVM storage device and started DRBD: # lvcreate

Hi all, In threads posted by I believe Jonathan Tripley I promised to post my new XEN HA setup. Hope it can be of some use to some people. In this particular case I''m forced to use SLES 10SP3 with XEN 3.2, which excludes the possibility of using things like cLVM (which I don''t think I need anyway). So: Storage: I use two HP ML370 G5 machines with DRBD and heartbeat on
